Be it lmown that I, ARTHUR R. DOUGLASS, a citizeri' of the United:States of America, and a resident of Chariton, county of Lucas, Stateof Iowa, have invented certain new and useful Improvements inMop-Wringe'rs, of which the following is afull and clear specification,reference being. had to the accompanying'drawings, in which.

Figure l-is a side elevation; Fig. 2 a rear elevation; and Fig." 3' aplan view of a mop embodying myinvention. Fig. 4:. is a perspective viewof a former upon which the coils of the wringing device may be wound togive to the wringer device the desired shape. 7

The object of this invention is'to so construct the device that it willserve to quickly and effectively squeeze water out of mop cloths, theconstruction of the device being such that it may preferably be madeof asingle piece of stout wire suitably twisted and coiled, as more fullyhereinafter set forth.

The standard (1 consists of two strands of stout wire twisted closelytogether to form a substantially rigid upright member, the two strandsat the bottom being separated and formed into a'fiat loop 6 adapted torest upon the floor and serve as a foot or base piece. The upper end ofthe twisted standard is bent downwardly to form a loop 0 which isadapted to engage over the edge of a bucket, the part cl which dependsinto the bucket being in turn curved upwardly at its lower end, thisupwardly-turned end being connected to the wringing device proper. Thiswringing device consistsof two wires 6 which are formed of integral'continuations of the two wires of the twisted part cl.

The two wires e are formed in two spirals which rise from their point ofconnection to the part d, the coils gradually increasing in diametertoward the top, thus forming a re-' ceptacle for the mop cloths which isapproximately conical. The upper extremities of the wires 6 are eachconnected to the top coil of the other wire, at f, by simply wrappingthe extremity of the wire around the top coil, said top coils beingflattened, whereby the top of the wringer will be horizontal and willconsist virtually of a single horizontal coil, the fastening of the endsof the coils at 7 giving to the top the, necessary rigidity.

this fiQOnadJfiGent tothe bucket, ,thevstandard sufiiciently. hi h toenabletthegoose neckmember (Z to spend into the bucket,

- as shown in Fig. 1." The footi'ofthe-juser is placed upon the basemember Z) to hold the device steady, and thenthe mop cloths are 7lowered into the uppe'ropen mouth of the eonlcal wringer. Then byturning the handle and pressing down on the'mop' lightly,

the coils 6 will act in the nature of a screw thread and cause. themopclothsto work gradually down until they wedge between the lower coils ofthe wires 6, thereby squeezing the water out; of the cloths with a firmbut yielding pressure. After this wringing operation, the mop may bereadily "removed from the wringer by simply turning the handle in theopposite direction. To increase the squeezing action on the cloths, Iflatten I the coils of the wires 6 at opposite sides, as

shown in Fig. 3, and to still further increase 7 the squeezing action ofthe coils I preferably shape them on a former or core 9 having a concavesurface, such as shown in ,Fig. 4. By thus flattening the. coils atopposite sides, it will be seenthat as the mop is turned these flattenedportions will exert an especially heavy pressure upon the mop cloth,while the parts of the cloth engagedby the su'fliciently heavy squeezingpressure to prevent the inop from being freely turned by the operator.Thus flattening the coils at opposite sides is further advantageousforother. parts of the coils will not be given a the reason that while itgives ample room for'the insertion of the mop cloths into the wringer,it at the same time materially avoids obstructing the entrance to-thepail, this being clearly apparent from an inspectionof Fig.3, in whichthe dotted circles indicate the rim of the pail, thus not only providinga wringer device of ample capacity. but also giving ample room fordipping the mop into the pail. i

7 It will be observed further that'I provide an approximately comicallyshaped receiver for the cloths, which receiver is flattened on Iopposite sides to give the coils an approximately oval shape in plan,the major axis of the coil ovals being at approximately right i.

anglesto the vertical plane of the support- 1 ing standard, whereby theconical receptacle will be disposed near the edgeof the'pail and thusleave the greater part of the mouth of the pail free for insertion ofthe mop into the pail. 7 Having thus described my invention, what Iclaim is:

1. A mop wringer consisting of a single strand of wire formed into abase loop, a

twisted standard whose upper end is bent downwardly so as to depend intothe bucket, the lower end of this downwardly-bent part being in turnbent upwardly and the wires of this upwardly-bent part being extendedupwardly and formed into spirals whose coils widen upwardly, the upperextremities of each of said wiresbeing connected to the top coil of theother wire.

2. A mop wringer consisting of a means for supporting the wringingdevice in the pail, and the wringing device consisting of two upstandingspiral wires Whose coils widen upwardly and are flattened at oppositesides to give the coils an approximately oval shape in plan.

In testimony whereof I hereunto afiiX my signature.
